BOTTLE-SEAL.

SPECIFICATION forming part of Letters Patent No. 756,715, dated April 5, 1904.

Application filed October Z, 1903.

To a/ZZ whom/ it may concern,.-

Be it known that I, EDWARD D. SCHMITT, a citizen of the United States, residing in the city of Baltimore, in the State of Maryland,

have invented certain new and useful Improvements in Bottle-Seals, of which the following is a specification. This invention relates to new and useful improvements in bottle-seals, especially adapted to sealing bottles containing liquids under pressure. In this art after the provision of a perfectly air-tight seal it is of paramount importance that the construction of the seal be Such that it can be cheaply manufactured, this in view of the fact that the seals are thrown away after being removed from the bottle or seldom, if ever, reused, thus entailing more or less loss, according to the cost of manufacture. My object, therefore, is to provide a perfect seal that will stand the internal bottle-pressure under all conditions, and one that will meet the requirement of cheapness as well as the minor requirements of being readily applied and removed and sightly in appearance. The further object is to provide a seal that can be readily applied without the aid of complicated machinery and which will require but a single operation for its application, the seal after being inserted in thebottle-neck requiring no further operation or treatment, such as iiexing, crimping, spinning or expanding. l

A still further object is to provide a closure embodying such construction as to permit the ready engagement with an unsealing-tool and one that will prevent the liquid from coming in contact with the metallic portion of the seal and which will afford no opportunity for the accumulation of dust, dirt, or other foreign matter.

Figure 1 is a central vertical section of the upper portion of a bottle-neck with which the seal is adapted for use, with the seal above the same also in section. Eig. 2 is a section of the bottle neck and seal, showing the latter applied. Eig. 3 is a sectional view of the bottle neck and seal, showing the manner of in- Serting an implemement for removing the seal.

Serial No. 175,522. (No model.)

Eig. 4 is a top plan view of the seal, more clearly showing the yielding portion which is engaged by the tool or implement in the unsealing operation. Eig. 5 is a top plan view of the securing member, showing the rim slitted Eig. 6 is a top plan view of the securing member, showing a modified form of means for affording engagement with a tool for unsealing purposes; and Eig. 7 is a side elevation of the modified form of seal shown in Eig. 6.

Referring to the drawings, thenumeral 1 designates the neck of a bottle which I provide with a sealing-seat 2 and a slightly in- -wardlyinclined wall or shoulder 3 above said seat, thereby producing at the rim or edge of the bottle a mouth of less diameter than the space between the walls below said mouth, all for a purpose that will presently become apparent.

The numeral 4 indicates the securing member, formed, preferably, of sheet-tin, with a slightly-raised central portion 5 and a circumferential rim or flange 6, adapted to impinge against the inclined wall in the bottle-neck when the seal is applied, as shown in Figs. 2 and 3. In order to permit the convenient insertion of a pointed tool for removing the seal, I cut or punch the central portion of the securing member to form a yielding portion 7, preferably held to the securing member by a narrow integral portion 7, or said yielding portion need not be cut entirely through the securing member, but sufficiently so to weaken it considerably, so that it will readily yield upon being engaged by the sealremoving tool. The form of the central yielding portion shown is the one I prefer, although it is obvious that the metal of the securing member could be cut or weakened at any desired point or in any desired shape and it would serve its purpose equally as well, or a narrow slit may be left in the securing member for the passage of a tool, if found desirable.

In the slightly-raised central portion 5 of the securing member I cement or otherwise secure the sealing memberS, which is pref- 95 erab'ly of cork, which is the material best adapted for sealing purposes, yet any suiificiently-compressible material 4would answer the purpose. I find in practice that by slightly raising the securing member to form the portion 5 lthe sealing member or disk is more readily centered ,than if the top of the securing member were perfectly fiat; but even this is not absolutely essential, for with accurate machinery for attaching the securing member to the sealing member the latter could be read'- ily centered. n

In the modification, Fig. 5, the securing member is identical with that shown in the main figures, except the rim is slitted at intervals, which renders the same a little more resilient, which characteristic may under some conditions be desirable.

In the modification shown in Fig. 6I provide the securing member with a central knob 9, that may be readily engaged by a forked tool for the purpose of removing the seal.

To apply the seal, it is only necessary to force the same into the bottle-mouth by any suitable tool or mechanism until the upturned rim or flange is compressed suiiicient-ly to permit its passage through the contracted portion of the mouth, when with the continuation of a downward pressure on the seal the sealing member will be brought in contact with the sealing-seat and the rim or flange will expand into locking engagement with the inclined wall 3, thus locking. the seal firmly in place. rIo remove the seal, as before indicated or suggested, it is only necessary to engage the yielding portion 7 with a suitable tool, which with the use of sufficient force will yield to permit the passage of the tool with which the seal can be easily pried out.

I claim- 1. A bottle-seal comprising a securing member formed with a circumferential rim or flange upturned and substantially semicircular in cross-section, and means for affording engagement with a suitable tool for removing the seal.

2. A bottle-seal comprising a metallic securing member having an integral circumferential rim or flange, said rim or flangebeing upturned and substantially semicircular in cross-section, a sealing member carried by the securing member, and means for aifording engagement with a suitable tool for ,removing the seal.

3. A bottle-seal comprising a securing member having an upturned circumferential rim or iiange and a yielding portion adapted to be engaged by a suitable tool for unsealing purposes, and a sealing member carried by the securing member.

4. In a bottle-seal, the combination with a bottle having a sealing-seat in the neck thereof bottle having a sealing-seat in the neck thereof,

and a wall above said seat inclining slightly inwardly and upwardly, a metallic securing member formed with an integral circumferential upturned rim or iiange adapted to impinge against said wall in the bottle-neck, a sealing member held in contact with the sealing-seat by the securing member, and means for aording engagement with a suitable tool for removing the seal, substantially as described.

6. In a bottle-seal, the combination with a bottle having a sealing-seat in the neck thereof, and a wall above said seat inclining slightly inwardly and upwardly, a metallic securing member formed with an integral circumferential elastic rim or flange adapted to impinge against said wall, a sealing member held in contact with the sealing-seat by the securing member, substantially as described.

7 In a bottle-seal, the combination with a bottle having a sealing-seat in the neck thereof, and a wall above said seat inclining slightly inwardly and upwardly, a metallic securing member formed with an integral circumferential elastic rim or fiange adapted to impinge against said wall, a sealing member held in contact with the sealing-seat by the securing member, and means for affording engagement with a suitable tool for removing the seal.

8. In a bottle-seal, the combination with abottle having a sealing-seat in the neck thereof, and a wall above said seat inclining slightly inwardly and upwardly, a metallic securing member formed with `an integral circumferential rim or flange adapted to impinge against the wall in the bottle-neck and a yielding portion adapted to be engaged by a suitable tool for unsealing purposes, substantially as described. I

9. In a bottle-seal, the combination with a bottle having a sealing-seat in the neck thereof and a wall thereabove and overhanging said seat and terminating therein, a securing member provided with an upturned rim or fiange engaging said wall, and a sealing member held in engagement with the sealing-seat by the securing member, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
